The avocado is a popular pear-shaped, green fruit that grows on the avocado tree (Persea americana). It is notable for its dark green outer shell that looks like alligator skin that protects a creamy pale green flesh surrounding a single seed. Mexico grows the majority of the world's avocados. It's most common in Latin American foods, including the very popular guacamole. The fruit can also be added to a variety of dishes, from salads and smoothies to sauces and even sweets. Avocados are packed with nutrition, easy to prepare—most often raw or pureed—and offer a creamy texture and mellow flavor that's irresistible.
